Scandir变量不是字符串？

Question

我有一段PHP代码列出目录，然后创建div，其中包含有关其内部目录的信息。但是，当我执行$ newsPieces [i]时，它不包含字符串中文件夹的名称，为什么？

$("#target").submit(function( event ) {
    event.preventDefault(); //prevent submit action here

    //Condition on checkbox
    if($( "input[name='product[6]']:checked" )){
        $('#submit-btn').click(); //handle submit if condition true
    }
});

修正版：

<?php
    $newsPieces = scandir("posts");
    for ($i = 2; $i < count($newsPieces) and $i < 10; $i++) {
        $titlefile = fopen($newsPieces[i] . "/title.txt", "r");
        $textfile = fopen($newsPieces[i] . "/text.txt", "r");
        $fullElement = "<div class='newsPiece'><div class='newsImageHolder'><img class='newsImage' src='" . $newsPieces[i] . "/image.jpg'></div><div class='newsContent'><h1 class='newsTitle'>" . fread($titlefile, filesize($newsPieces[i] . "/title.txt")) . "</h1><p class='newsText'>" . $piece[] = fread($textfile, filesize($newsPieces[i] . "/text.txt")) . "</p><a class='newsLink' href='post?post=" . urlencode($newsPieces[i]) . "'>Continue Reading</a></div></div>";
        echo $fullElement;
        fclose($titlefile);
        fclose($textfile);
    }
?>
